| 摘 要： | 煤层气井网开发必须进行排采，降低井内压力达到产气的目的。煤层气井的产气量取决于煤储层特性，但在排采时因受排采各参数以及井网排采井间相互干扰的制约，只有掌握产气量与这些参数的关系和井间各参数的关系才能合理的制定出井网开采工作制度。本文利用辽宁省阜新市刘家煤层气小井网排采试验资料，研究了该区各井产气量、井口压力和液面深度等参数间的关系，总结出了排采工作中各参数间及中心井与非中心井间的影响规律，为制定合理的排采工作制度提供了依据。

| Abstract: | Exploitation of coalbed gas in spacing pattern must carry out d ra inage and mining,and lowering pressure in the wells,thereby reach to the purpo se of gas production.The gas product depends on the properties of coal reservoi r,but restricted by parameters when drainage and gas mining,and also be restr icted by disturbance each other between wells of drainage and mining in spacing pattern,only if grasp relation of gas product with these parameters and relatio n of parameters between wells,may be lay down working rules of mining in spacin g pattern reasonably.The relations between parameters of gas product in each we ll,collar pressure,depth of level,and so forth have studied in the paper.The laws between parameters in the work of drainage and mining and the influence l aws between center well and uncenter well have summarized,which in favour of coalbed gas exploitation in spacing pattern from now on,and provided basis for lay down working rules of drainage and mining reasonably. |
